Having an issue with the heater in my 2000 Boxster S. It fogs up the windows when the heater is on. If I turn the AC button on the fog stops but the air temperature is no longer hot or warm even. The moisture coming out seems to have an odd smell to it. It's either old nasty water or perhaps antifreeze. Any help would be greatly appreciated.
Hi Guys, I finally narrowed my vacuum leak on my coolant system to heater core pipes. When I isolated heater core pipes near the split hose under rear passenger side, I could see vacuum holds at 25psi. So I am suspecting a hole or a hose leak at the heater core. I know heater core is under the battery, but wondering how to get to the heater core. Bentley manual does not cover this topic. Any help with instructions are appreciated.
